When I go to CPAN looking for a module XYZ::PQR; there is no other mechanism that will inform me that there is a later patched version of that module available from a different author that I might find better than the original.
Ah, ok, so, if I think I have a better idea on how to implement XYZ::PQR, I should just release a version of XYZ::PQR with a higher version number, just to draw attention that I have a "patched" version?
When is something a bug fix? What if it fixes a bug, but breaks someones else code? I guess you'll be saying "well, screw him, let him do the work, find the documentation this is patched version by another author, and let him download older version". But that's not something I would like to do.
Well, good for you. I have a conscience. I'll just pick another name, and I'm not arrogant enough that my patch is so fucking important as to the steal the name.
